![]() ![]() Online countdown clocks – which the CMA inferred as a contributing factor to so-called “pressure selling” – have been a major part of the ecommerce experience for many years – not just on travel sites, but across the wider retail ecosystem. But assuming businesses return to some degree of normality in the coming months, some of the tactics scrutinised by the CMA are worthy of focus by IMRG. Issues such as pressure selling, misleading discount claims, and the effect commission has on how hotels are ordered on websites were all under scrutiny.įollowing developments in the UK and around the world in recent weeks, the probe seems like a lifetime ago and, to be honest, somewhat irrelevant right now in the face of a global pandemic and an industry on a knife edge. ![]() ![]() Yet just last September, the online travel retail sector found itself wrapped up in a serious Competition and Markets Authority (CMA) probe about the tactics it used when interacting with customers on the web. The virus and the accompanying government guidance for consumers to reduce social contact and avoid non-essential trips to help prevent the spread of the disease is going to have untold consequences on retail – perhaps none more so than the travel sector, which has already grounded thousands of flights, closed accommodation, and – in some cases – laid off staff altogether. That is only natural, and the fast-moving nature of it all, and how commerce and society is changing as a result, will continue to hold the focus for the months ahead. Right now, I would argue there can be no individual or business in the UK who is thinking much further than how the global health emergency, brought on by the ongoing spread of the coronavirus, Covid-19, will impact their immediate future. It’s amazing what an industry deems important can change so dramatically in just a matter of weeks and months. ![]()

![]() ![]() Unlike PokerTracker 3, PokerTracker 4 was build from scratch and not just built on top of the former version. In 2013 PokerTracker released the latest version of their software, PokerTracker 4. PokerTracker continued to update PokerTracker 3for five years, fixing bugs, adding new features and improving the overall usage of the program. In 2009 PokerTracker released PokerTracker 3, which was build on the original design and interface of PokerTracker, but with support for many new sites and networks as well as new stats, improved reports and a better HUD. To keep up with a fast moving poker industry, constantly having new poker networks and sites opening as well as the need for more statistics and reports, PokerTracker have released new versions of their tracking software multiple times. It showed quickly that players using a tracking program gained a significant edge over the players not using any programs and soon poker tracking software had spread to all regular playing poker players. With this tool players started to examine their own game, finding leaks and optimizing their game for constant improvement in the fast moving online poker world. ![]() This provides players with real-time stats of their opponents, making it possible to adjust and exploit them.Īlong with Hold’em Manager, PokerTracker quickly became a popular tool for players to use, with a great interface, statistics, reports and customizable HUD. To make it easier for players to improve their game while playing and to obtain an edge on the players, PokerTracker has a Heads Up Display (HUD) on the tables, showing the most valuable stats while playing. PokerTracker wanted to create a easy to use poker tool to analyze patterns, win/loss, hand histories and expected value calculations. PokerTracker’s first version was created in 2007 by PokerTracker Software LLC and is an online poker analytics tool, helping players improve their game. ![]() ![]() This meant I had to make two major changes to the fundamental way Monodraw worked – introduce dynamic positioning and fully editable shapes. Tools should be empowering and allow you to easily create rather than forcing you to express yourself in their "language" (i.e., the abstractions they provide). I came to the realisation that the tool was fighting you rather than helping you – exactly the opposite of what was expected. For example, you could only edit the corners of a rectangle and if you wanted to change a single character, you had to create a separate surface shape, position it above and set a character there. This makes it harder to express the relationship between shapes, so you end up having to manually move and re-adjust them. The position of shapes could not be dynamically specified, apart from line end points. ![]() After the Monodraw reveal, we want back to drawing board and noticed two important shortcomings: ![]() The aim of the beta program is to release a build of the app that is not quite fully featured or polished but provides a solid foundation to build on. Next up, I want to explain why it has taken longer than expected to provide the first status update. Our customers deserve to be treated with respect and honesty. Always feel free to send me an email or just tweet one thing I can promise you is the truth – no corporate or marketing speak. It is my intention to provide regular updates on our blog so that you are not left in the dark, wondering what is happening – if you don't see any updates for a while, it probably means we are busy working and there is nothing that we can announce just yet. My mission is to be completely open about what's happening behind the scenes, what work is being done and what our plans are. It has taken a bit longer than I expected but we have made some significant progress and more importantly, completed some essential improvements to how the app works.īefore we go any further, I want to set out what you can expect from us when it comes to Monodraw's development. It is finally time for our first Monodraw beta progress update. ![]() ![]() ![]() ![]() It provides free CPUs and it’s similar to the Streamlit Cloud. Hugging Face Spaces is a service where you can deploy your Streamlit or Gradio applications so that you can easily share them.I suggest having a look at Gradio as well, which is another popular Python library with similar goals. Moreover, you can deploy your Streamlit application to the Streamlit Cloud, which makes it easy to share your applications with other people and you get free CPUs to run your applications. Check out the Streamlit Gallery to learn what can be done with the library. Streamlit is a Python library that allows data scientists to easily create small interactive demos, so that other people can test their machine learning models or see their data analyses. ![]() I am delighted that Generate is creating opportunities for testing programs that were not possible only a few months ago.” Saad Khan, PhD.I’ve been wanting to experiment with Streamlit and Hugging Face Spaces for a while now. Our users have also been delighted at how Generate has expanded their thinking by creating fresh content and new items and distractors that they had never even thought of. This is the underlying philosophy we embedded in creating Generate. “Computer scientists know that the best AI tools are those that can be used in a hybrid human-AI fashion by domain professionals. Ongoing research is centered on optimizing the client experience and new insights will be shared over the coming months. Generate’s proof of effectiveness has been robustly established both theoretically (presentations at Association of Test Publishers 2021 national conference and at the 2021 Educator’s Data Mining conference) and in practice with current partners. Based on our pilot partners’ feedback, they are too.” Steve Shapiro. As we continue that work we are thrilled at the advances our AI Center has made. “Over the past six years Finetune has developed a deep partnership with The College Board in building the AP Classroom platform serving millions of students and their teachers. Generate’s NLP algorithms develop high quality items at scale by mastering content domains based on a small, safe, and secure sample of existing items. Generate was developed in Finetune’s AI Center of Excellence, led by Saad Khan, PhD, a computer scientist and globally recognized expert in the application of Machine Learning to education and assessment. In addition, blind comparisons between samples of existing and Generate-developed items have resulted in Generate items receiving higher quality ratings on average. Generate’s power is applicable to any content (K-12 to advanced technical specialties like medicine or law) and to any program (education, certification and licensure, training, prep) for multiple purposes (formative to high stakes).Įarly adopters of Generate have reported impressive gains of 3x to 10x in productivity. Users point out that Generate excels where other approaches are weakest, particularly around coming up with novel and creative ways to sample domains and developing highly effective ways of measuring higher-order thinking skills. Importantly, Generate functions without templates therefore avoiding the cost, time, and psychometric disadvantages of automated item generation (AIG) tools. Generate employs state-of-the-art artificial intelligence (AI) and natural language processing (NLP) to recommend novel, creative and conceptually-accurate assessment passages, stems, and distractors. ![]() Finetune, a global educational technology company, announces the release of Finetune Generate ®, a groundbreaking AI product that was shown to increase subject matter experts’ (SME) authoring speed up to 10x while concurrently improving item quality and creativity. ![]() ![]() It supports 100+ Data Sources such as MongoDB, including 40+ Free Sources. ![]() Hevo Data, a No-code Data Pipeline, helps load data from any data source such as Databases, SaaS applications, Cloud Storage, SDK,s, and Streaming Services and simplifies the ETL process. Read MongoDB Compass Blog to understand in detail about MongoDB Compass. To maintain performance and scale horizontally, create clusters with real-time replication and shard big or high-throughput collections across many clusters. MongoDB is a distributed database that was built from the ground up. With just a few lines of JSON-like MQL, you can query deep into documents and even run complicated analytics pipelines. How useful is data if you can’t search for information in it? MongoDB is created to make data easy to find and rarely requires joins or transactions, but it’s more than capable of handling sophisticated queries. Changing schemas doesn’t require any downtime, and you can begin adding new data to MongoDB at any time without interrupting its processes. MongoDB puts a lot of effort into building efficient methods and learning from our failures, but the database is usually the constraint. If you’re used to wanting to take your site or app offline in an attempt to change the format of your data, MongoDB is built to change. ![]() MongoDB’s decision to store and represent data in a document format implies that you may access it in any language, using native data structures such as Python dictionaries, Java Maps, etc. To get data into Object form for usage in programs, most databases require the use of heavy wrappers such as ORMs (Object Relational Mappers). MongoDB allows you to create specific schemas and validate data to keep things under control, but its flexibility is invaluable when dealing with real-world data and dealing with changes in needs or environment. ![]() MongoDB’s BSON data format, which is based on JSON, allows you to have objects with multiple sets of fields in the same collection. MongoDB’s document model makes it simple to model and manipulate nearly any type of data structure. Key Features of MongoDB Compass 1) Flexible Document Schemas
![]() ![]() You now can locate the three altitudes of every type of triangle if they are already drawn for you, or you can construct altitudes for every type of triangle. Now that you have worked through this lesson, you are able to recognize and name the different types of triangles based on their sides and angles. Since every triangle can be classified by its sides or angles, try focusing on the angles:įor oblique, acute triangles: the altitudes will always be inside the triangleįor oblique, obtuse triangles: the altitude dropped from the obtuse angle will be inside the triangle and the other two altitudes will fall outside the triangleįor right triangles, two of the altitudes are the legs and the third altitude is inside the triangle Where to look for altitudes depends on the classification of triangle. Picture right △ R Y T \triangle RYT △ R Y T with the hypotenuse stretching horizontally.Ĭan you see how constructing an altitude from ∠ R \angle R ∠ R down to side YT will divide the original, big right triangle into two smaller right triangles? Use Pythagoras again! Where to look for the altitude But what about the third altitude of a right triangle? The other leg of the right triangle is the altitude of the equilateral triangle, so solve using the Pythagorean Theorem:Ī = 20.7846 y d s a=20.7846 yds a = 20.7846 y d sĪnytime you can construct an altitude that cuts your original triangle into two right triangles, Pythagoras will do the trick! Use the Pythagorean Theorem for finding all altitudes of all equilateral and isosceles triangles.įor right triangles, two of the altitudes of a right triangle are the legs themselves. You only need to know its altitude.Ĭonstructing an altitude from any base divides the equilateral triangle into two right triangles, each one of which has a hypotenuse equal to the original equilateral triangle's side, and a leg 1 2 \frac 2 1 that length. It will have three congruent altitudes, so no matter which direction you put that in a shipping box, it will fit. Imagine △ E Q U \triangle EQU △ EQ U with sides labeled 24 yards. What about an equilateral triangle, with three congruent sides and three congruent angles. Not every triangle is as fussy as a scalene, obtuse triangle. What about the other two altitudes? If you insisted on using side GU ( ∠ D \angle D ∠ D) for the altitude, you would need a box 9.37 cm tall, and if you rotated the triangle to use side DG ( ∠ U \angle U ∠ U), your altitude there is 7.56 cm tall. You would naturally pick the altitude or height that allowed you to ship your triangle in the smallest rectangular carton, so you could stack a lot on a shelf.Īltitude for side UD ( ∠ G \angle G ∠ G) is only 4.3 cm. Think of building and packing triangles again. Obtuse triangles - One interior angle is obtuse, or greater than 90°Įvery triangle has three altitudes. Oblique triangles break down into two types:Īcute triangles - All interior angles are acute, or each less than 90° Right - One right angle ( 90°) and two acute angles Anglesīy their interior angles, triangles have other classifications: Most mathematicians agree that the classic equilateral triangle can also be considered an isosceles triangle, because an equilateral triangle has two congruent sides. ![]() Scalene - No two sides are congruent (equal in length) By their sides, you can break them down like this: Sides You can classify triangles either by their sides or their angles. ![]() A triangle gets its name from its three interior angles. To find the altitude, we first need to know what kind of triangle we are dealing with. To get the altitude for ∠ D \angle D ∠ D, you must extend the side GU far past the triangle and construct the altitude far to the right of the triangle. To get that altitude, you need to project a line from side DG out very far past the left of the triangle itself. The altitude from ∠ G \angle G ∠ G drops down and is perpendicular to UD, but what about the altitude for ∠ U \angle U ∠ U? Label the sides too side GU=17 cm, UD=37 cm, and DG=21 cm.įor △ G U D \triangle GUD △ G U D, no two sides are equal and one angle is greater than 90°, so you know you have a scalene, obtuse (oblique) triangle. We can construct three different altitudes, one from each vertex.ĭraw a scalene △GUD with ∠G=154°, ∠U=14.8°, and ∠D=11.8°. Here is scalene △ G U D \triangle GUD △ G U D. The height or altitude of a triangle depends on which base you use for a measurement. How big a rectangular box would you need? Your triangle has length, but what is its height? Imagine you ran a business making and sending out triangles, and each had to be put in a rectangular cardboard shipping carton. An altitude is a line drawn from a triangle's vertex down to the opposite base, so that the constructed line is perpendicular to the base. ![]() ![]() ![]() ![]() ![]() The creators of tools sold in market sectors like customer data platforms, customer relations managers and data management platforms all want to help companies curate their interactions with customers and they’ve been integrating AI in different ways at different layers.Īt the same time, some developers are shipping more basic tools that other developers can integrate into their own applications. The tools for creating the bots are now fairly common in the front lines of businesses, and now much of the effort is devoted to finding the best channel for delivering the technology - which is reflected in Cresta’s announcement today. These are one of the first places where AI scientists looked to apply their work in natural language processing (NLP). Conversational AI competition is heating upĪ number of companies are actively trying to automate this space because customer service inquiries are expensive and sometimes fraught with political minefields with many dangers for missteps. “Cresta’s AI-solutions make agents faster and enable self-service automation, so businesses can finally improve on every interaction while also improving operational efficiency.” continued Kolman. The agents are said to save three to five hours in an average week by letting Cresta’s tools do repetitive tasks. Startup and training time for new agents was cut by a factor of three. Customer satisfaction ratings (CSAT) increased by 15% in the company’s tests. “All of this is invisible to the end customer.”Ĭresta claims that its platforms can boost several metrics. “ enables companies who purchase the Zoom Contact Center, along with Cresta, to use real-time transcription to guide the agent in their engagement process with the customer to do things such as sell more though better adherence to the company’s sales playbook, or to more quickly resolve customer issues.” explained Scott Kolman, the CMO at Cresta.

Sometimes it is very difficult to memorize the atomic mass of the heavy elements and in such cases, it is best to see a periodic table to get accurate results. The very first thing while determining the molar mass of a compound is to look at the molecular weight of individual elements in the periodic table. In fact, Sodium Chloride has a lot of industrial applications such as in the soda ash industry or the chlor-alkali process and thus, knowing the molar mass of NaCl is very important. Its many applications include that of a food preservative and for de-icing of pathways and highways. Scientifically known as Sodium Chloride and fondly referred to as common salt, NaCl is a compound responsible for making up the extracellular fluids in most cellular organisms and causing the salinity in seawater. NaCl consists of a lattice of Na+ and Cl- ions which react in the ratio of 1:1 to give us halite or salt. The compound NaCl is composed of two elements, sodium (Na) and Chlorine (Cl) and together when they react chemically, they form NaCl as the product. Let us take the example of the molar mass of NaCl. Compounds are basically substances that are formed when two or more elements react chemically while elements, on the other hand, are naturally occurring substances found mostly in abundance on Earth or in the atmosphere. That is, the molar mass of a substance= 1 gram/I moleĬalculating the molar mass of NaCl can be extremely simple only if you know the difference between elements and compound and have a knowledge about the molecular weight of the respective elements. The molar mass of a compound is also known as its molecular weight and is the total mass in grams of the atoms that form one mole of a certain molecule. ![]() Once we are aware of the moles required for a particular experiment, we can easily use the concept and notion of molar mass for determining the grams of substance required for our purpose. A mole is nothing, but a unit used for measurement which helps in comparing particles and mass of a given compound. After various calculations and observations, a scientist discovers the number of moles required for a particular experiment based on which we calculate the molar mass. For all laboratory calculations, a tool called the analytical balance is used to measure the weights in grams. ![]() Thus, a change in the molecular mass of a compound can greatly vary the results of any scientific calculations. It becomes essential that we measure these molecules in all the experiments to get accurate results for our products in the experiment. We know that all things around us are occupied by matter whose building block is molecules. Before we begin to calculate the molar mass of NaCl or any other compound for that matter, it is important that we know what exactly the molar mass of an element is. ![]() ![]() ![]() Cancel Renewal: To cancel automatic renewal, please cancel 24 hours before the current subscription cycle expires.

In some cases, you need to use multiple techniques. Integral helps you make the most of your time, allowing you to focus on. If none of the above techniques work, you should take some more aggressive measures advanced algebraic manipulations, trig identities, integration by parts with no product (assume 1 as a multiplier). Multiple definitions: 1)The general word used to describe the entire pool of.including forcing numerical output and multiple definitions of a function with different numbers. Radicals: use trig substitution if the integral contains sqrt(a^2 x^2) or sqrt(x^2-a^2), for (ax b)^1/n try simple substitution. Mathematica Notebooks for Probability and Statistics.Product of a polynomial and a transcendental function: use Integration by parts.Rational functions: use partial fractions if the degree of the numerator is less than the degree of the denominator, otherwise use long division.Notice that integrating f(x, y) with respect to y is the inverse operation of taking the partial derivative of f(x, y) with respect to y. If you can’t solve the integral using simplification or substitution, try to classify the integrand into one of the following: product of trig powers, rational functions, radicals, or a product of a polynomial and a transcendental function. This process of going through two iterations of integrals is called double integration, and the last expression in Equation 3.1.1 is called a double integral.
